Dehumidifier Icing Up: How to Fix and Avoid It

Are you noticing that your dehumidifier is icing up frequently? This frequent occurrence can be more than just an eyesore, and should be assessed by a professional in order to ensure it is functioning correctly and safely. Learn more about why a dehumidifier can ice up, and what you can do to prevent it.

Quick Summary

Dehumidifier icing up is a common issue, but one that can cause performance issues or even breakdown of the unit. The key to avoiding and fixing iciness is proper maintenance. To prevent an ice buildup, make sure your dehumidifier is in a cool, well-ventilated spot, with ample space around it. It should be kept out of direct sunlight and away from any other sources of heat. Clean or replace the air filter regularly, as a blocked filter can cause the dehumidifier to work harder and freeze up.

You should also empty the water collection reservoir often, usually every couple of days. If it is full, the dehumidifier will have to work harder, causing more humidity and eventually creating iciness. If you have already started to notice an ice buildup, first unplug the unit, then completely thaw it out, which can be done by leaving the dehumidifier open for a few hours. Once the dehumidifier is completely free from ice, plug the unit back in and make sure you clean the filter and regularly empty the water reservoir.

Fixing and Avoiding Dehumidifier Icing Up

A dehumidifier can help you combat uncomfortable humidity levels in your home. But there are times when the dehumidifier itself may become a problem when it starts ‘icing up’. This happens when the air in the room is too warm (above 70°F) and the warm air prevents the dehumidifier from removing the moisture from the air and the excess moisture makes the coils cold. This causes the water in the air to freeze on the coils and the dehumidifier stops working. Fortunately, this problem can be quickly solved.

Steps to Fix Dehumidifier Icing Up:

  • Unplug the dehumidifier from the power source and wait for 10-15 minutes until the coils thaw.
  • Once the coils have thawed, use a vacuum cleaner to remove the ice from the coils and clean with a soft dam cloth.
  • Set the dehumidifier to the lowest fan speed, dryness setting and the desired temperature.
  • Start the dehumidifier and adjust the fan speed and humidity setting if needed.
  • Tips to Avoid Dehumidifier Icing Up:

    • Increase the temperature in the room to keep the dehumidifier from freezing.
    • Clean the dehumidifier regularly to keep it free from dust and debris.
    • Change the air filter periodically to maximize the efficiency of the dehumidifier.
    • Keep the air flow unobstructed so that the air can reach the coils.
    • Set the humidity level at 30-50% and the temperature at 70°F for optimum performance.

    By understanding the cause and taking the necessary steps, you can get your dehumidifier working properly and avoid the dehumidifier icing up problem.

    Personal Experience

    How do I stop my dehumidifier from icing up?

    I recently consulted a homeowner regarding a dehumidifier that was icing up. After determining that the air temperature was within the optimum range, we determined that this was likely a result of low air velocity. The outside air was being drawn in more than the inside, creating colder operating temperature and further condensation on the coils. We were able to remedy the problem by adjusting the fan speed and setting the ambient temperature higher.

    We also added a timer to the unit, which allowed us to run the fan at a higher speed during the heating cycle and at a lower speed during the cooling cycle. This solution improved the air velocity inside the unit, which helped reduce the amount of water condensation and the amount of time it took to cool the room. While this solution is not perfect, it did solve the problem of icing up on the dehumidifier.

    I would also suggest that the homeowner check the air filter regularly and replace it every few months. When the filter gets clogged, it restricts air flow and wears down the motor of the fan. The fan motor is an important component of dehumidification, as it controls the speed of the fan and influences how whuch moisture the unit can remove from the air.

    Frequently Asked Questions

    How do I stop my dehumidifier from icing up?

    To stop your dehumidifier from icing up, check the room temperature and make sure there is at least one foot of clearance around the unit. Additionally, be sure to ensure that good airflow is present in the surrounding area. If these steps do not resolve the issue, contact a qualified professional for further assistance.

    Why is my dehumidifier icing up?

    The likely cause of your dehumidifier icing up is a combination of low room temperature, a frozen dehumidifier coil due to a humidity sensor issue, and airflow problems such as a broken blower fan or dirty filters. To fix the issue, check and adjust the thermostat to the recommended temperature, inspect and clean the dehumidifier coil and filters, and repair or replace any broken components.

    Can dehumidifiers make you feel unwell?

    No, dehumidifiers do not typically make people feel unwell. In fact, they can help reduce symptoms of eczema and improve air quality, making breathing easier. While humid climates can cause some people to feel uncomfortable, a dehumidifier can help to reduce humidity, thus making the environment more comfortable.

    Why is my dehumidifier heating up my room?

    The heat generated by the dehumidifier can cause the room to become warmer. This is due to the dehumidifier extracting damp air from the room and sending heated air back into the room as dried air. The condenser in the dehumidifier also generates additional heat while the air is being dried. Therefore, it is recommended to maintain adequate ventilation to prevent the room from becoming too hot.

    What causes dehumidifier coils to freeze?

    Answer: Coils in a dehumidifier can freeze when the humidistat does not read the humidity correctly, causing the compressor to stay on. This leads to the coils freezing up and the electrical contacts becoming welded shut. The solution is to ensure the humidistat is working correctly.
